Chapter 1: The Dilemma of Over-Engineering

Software engineers often fall into the trap of over-engineering solutions, a tendency I can acknowledge as a fellow developer.

It's common to try to anticipate numerous future scenarios, which can lead to overly complex designs. As junior developers, we typically lack awareness of potential challenges that may arise later. Initially, we may code in a simplistic manner, but as we stick with a project, we discover that as requirements evolve, our designs may not hold up.

Through experience, we learn from our missteps. We tell ourselves, "Next time, I’ll ensure my design accommodates these possibilities." However, this cycle tends to repeat itself. As we gain experience, we often find ourselves continually adding layers of robustness, flexibility, and scalability to our designs.

Eventually, many of us recognize that this tendency to over-engineer can be detrimental. The pursuit of infinite flexibility often leads to unnecessary complexity and additional workload for scenarios that might never occur. This raises the question: how many projects fail to launch due to such challenges?

I fully admit to being guilty of this mindset. One of my preferred design patterns involves using plugins to facilitate scalability in feature sets.

Chapter 2: Finding the Right Balance

So, what’s the solution? Unfortunately, there isn’t a one-size-fits-all answer. It’s essential to discover a balance that works for your specific context, considering factors like product type, team dynamics, programming languages, and tools.

For me, I often find success by starting with plugins when I see a consistent theme of features that I want to extend. For instance, when developing web APIs with multiple endpoints, I organize routes by feature area into a plugin. This approach allows me to either add routes to an existing feature area or create a new plugin for a different feature area.

This pattern is effective because I understand the implications of my choices. However, if I were to take this approach to an extreme, creating a dedicated plugin for every possible route, the resulting complexity would likely outweigh any benefits.

When onboarding new team members, especially those I've not worked with before, I prefer to take some time to align on these principles upfront. It’s advisable to have similar discussions with your team to pinpoint where the balance lies and how it might shift.

A gentle reminder: if you’re in the rapid prototyping phase—which is often the case and frequently leads to discarded work—there’s no need to design for extensibility. Chances are, you’ll be rewriting your proof of concept rather than extending it.

What strategies do you employ to find this balance?
